SYLVANWI To all whom it may concern: i

Be it known that I, Cmnrnn'r F. 8mm, a citizen of the UnitedSta-tes,residing at Schenectady, in the county-Of Schenectady and State of NewYork, have invented new and usual Improvementsin' Controller-Cam.I)cvices,of which the following is a specification. 1

- This invention relates to means for supplying fluid pressureintermittently or periodically. for any suitable purpose where it isdesired to utilize the fiuid under pressure in a series of blasts ofgreater or less frequency and duration, and has for its object toprovide an improved lever'devioe for controlling the intensity of theblast or for cutting off the same altogther.

\Vhile my improvement is adapted for a variety of uses, it isparticularly designed to be employed'in connection with a mechanicalstoker for forcing the fuel into the firebox, as shown and described inmy prior pending application Ser. No. 565,579, filed June 7, 1910. Inthis prior construction, the admission of fluid under pressure to thefuel (listributer nozzlesis controlled by a .valve operated by a pivotedlever one end of pon the pe riphery of a cain-diskupon which the cammembers are pivoted and adapted to be turned to different positions toextend vthe difl'erent cam surfaces beyond the periphery of the disk toengage the roller and actuate the valve. Y I

According to 'my present improvement,

the connection between thevalve lever and valve may have adjustablemeansfor varying the extent-of opening of the valve, and the intensityof the blast, or for disconnecting the same altogether when it isdesired to throw thedevice out of o ration.

Iuthe accompanying rawing, the figure is a front elevation of myimproved device, the valve being shown in'section.

As setforth in my prior application, the valve for controlling thesupply or flow of the fluid under pressure comprises a casing, 32,containing a valve proper, 31, with stem, 34. and a 3 )ring, 33,normally holding the valve clo on its seat, the casing having a bracketarm, 37, to which is pivoted the lever 36 ada ted to operate the valvestem and at the. ot er end carrying a roller which bears against the camdisk.

As shown inthe drawin a cam disk, -35,-

provided' with a plurality 0 "adjustable cam members, 40, havinghandles, 42, movable in slots, 50, is employed for imparting movement tothe lever, but" any'other'suitable means forosoillating said lever-maybe-used, if referred: v 1

. en the cams are adjusted to give any desired flow of fluid the devicemay be cut out of operation at any instant, if necessary, by merelysliding the movablelatch, 38, on the' lever, 36, fromhif'dpmfi 1 tion,as shown, in which it engages the valve stem 34, to its inoperativeposition, as indicated in dotted lines. The valve then remains closedalthou h the cams may continue to actuate the Iever. This avoids thenecessity of disturbing the adjustment of the cams, when for any reasonit is desired to temporarily cut the device out of operation.

The latch may also be provided with stops of different lengths adaptedto effect different degrees of opening of the valve, ,as ixidi- 1 catedin the figure, whereby the intensity of the fluid blasts for any givenadjustment of cams may be readily varied,-as desired, by merely shiftingthe latch to one or another of its difl'erent o erative positions inwhich Having now described my invention, what I claim as new and desireto secure by Letters Patent, is:

1 In a controller cam device, the combination with a valve forcontrollin the supply of fluid pressure and a lever or actuating thesame, of a cam disk having cam members for operating said lever, and anadjustable latch mounted on the lever for engaging or disengaging thevalve connection.

2- In a controller cam device, the combination with a valve forcontrolling the flow of fluid, a lever for actuating the same, and acontinuously operating cam for actuating mainta ner 1, 191.5;

said lever, of a manually adjustable means for temporarily disenga ingthe connection between said lever and t e valve.

3. In a controller cam device, the combination with a valve forcontrolling the flow of fluid, a lever for actuating the same, and acontinuously operating cam for actuating said lever, of manuallyoperated means for adjusting the connection between the lever and valvefor varying the intensity of the fluid blasts.

4. In a controller cam device, the combination with a valve forcontrolling the flow of fluid, a lever for actuating the same, and acontinuously operating cam for actuating said lever, of a latch devicebetween said lever and valve for adjusting the extent of valve openingor for disengaging the connection.

5. In a controller cam device, the combination with a valve forcontrolling the flow of fluid, a lever for actuating the same, and acontinuously operating cam for actuating said lever, of an adjustablelatch device mounted on said lever and having stops of difl'erentlengths for engaging the valve.

6. The combination of a valve for controlling a fluid su ply and havinga projecting stem, a lever or opening said valve, and an adjustablecontact member carried by the lever for engaging said valve stem.

7. The combination of a valve for controlling a fluid supply and havinga projecting stem, a lever for opening said valve, means for oscillatingsaid lever, and an adjustable contact member carried by the lever andhaving sto s of different lengths for engaging said va ve stem.
